SPECIFICATION forming part of Letters Patent No. 471,766, dated March29, 1892.

Application filed November 17, 1891. Serial No. 412,176. (No model.)

To a/ZZ whom it may concern.-

Be. it known th'at we, DAVID PATTON BUR- DON and SAMUEL HOUSTON,citizens of the United States, residing at Jacksonville, in the countyof Duval and State of Florida, have invented a new and usefulAir-Compressor Motor, of which the following is a specification.

-This invention relates to mechanical motors used in connection withair-compressors; and it has for its object to provide a machine whichwill automatically operate ordinary airengines which are used tomaintain appressure for forcing air upon liquids to transfer the samefrom one vessel to the other, for keeping an equal and steady pressureof air for blast purposes, and for'any other purpose whereit isnecessary that a steady and equal pressure should be always employed,and to this end providing mechanism for auto'- matically operating suchdevices which will maintaina steady pressure at all times within thelimit of the power of the machine.

With these and other objects in view, which will be readily apparent asthe nature of the invention is better understood, the invention consistsin the improved motorand mechanical movements actuated therebyhereinafter more fully described, illustrated in the accompanyingdrawings, and specifically pointed out in the appended claims.

In the accompanying drawings, Figure l is a side elevation of anair-compressor motor or mechanism constructed in accordance with thisinvention. Fig. 2 is a top plan View of the same, the escapements andactuating Inotor being detached from the same. Fig. 3 is an endelevation of the machine with the motor removed therefrom. Fig. 4 is adetail elevation of the spring power or motor.

Referring to the accompanying drawings, A represents the bases uponwhich are supported the opposite pair of air-compression cylinders B,constructed in the usual manner and connected with the devices to whichair under pressure is designed to be supplied. The said cylinders areprovided with the ordinary pistons and valves, the pistons beingconnected by the parallel continuous rods or stems C, which connectthepistons of the opposite cylinders in parallel pairs, and each piston-rodis provided withthe intermediate tappets or shoes D and D',respectively, each of which is provided with the inner square, recessedportions d and CZ', which are engaged by the mechanism to be described,and which actuate, alternately, each continuous pistonrod. Upon suitablesupports adjacent to the said cylinders are the stationary transverseshafts E, supported over each end pair of the cylinders andaccommodating the large gear-kv wheelsF and F', loosely mountedthereon'and adapted to be revolved by means of the motor located at oneend of the cylinders, as illustrated, or underneath, if desired, andconnected with the gear-wheel F in the manner which will be hereinafterfully set forth. Each of the intermeshing gear-wheels F and F isprovided with the contact friction-rollers G, journaled upon the pins g,projecting alternately from opposite sides of the rims of each wheel.Thev said rollers are arranged upon each wheel, so that those upon oneside are alternately disposed with'relation to those upon the same sideof the intermeshing wheel, while the rollers upon the opposite side ofthe wheel are similarly disposed with relation to those upon the sameside of the adjacent wheel, which arrangement is for the purpose ofsecuring the proper alternate reciprocation of the piston-rods C'through the medium of the escapement-levers H and H', respectively. Thesaid levers H and H'- are connected .with suitable bearings h and h',which oscillate upon the transverse shaft I, supported in suitablebearings in a suitable frame-work designed for its reception. The saidlevers are further provided at their extreme lower ends with theoutwardly-projecting pins h2, upon which are mounted thefriction-rollers h3, that snugly take within the squared recesses d andd' in the opposite tappets D and D', and thereby as the said levers areoscillated cause the alternate reciprocation of the continuouspistonrods. Each of the escapement-levers H and l-l' depends from theshaft I centrally between the intermeshing gear-wheels upon both sidesthereof, and secured upon the inner faces are the downwardlyextendingand diverging wings h4 and h5, that are engaged by the friction-rollersupon each side of the said gearwheels, and thus cause a swinging oroscillatory motion to be given to the levers. The contactfriction-rollers traveling upon said contact-Wings are so disposed thatjust as the friction-roller upon one side of one of the largegear-Wheels has just left the lowerniost point of one of the Wingsandhas thereby carrled the piston-rod to one end of its stroke one ofsaid contact-rollers upon the same side of the adjacent gear-Wheel hasjust begun its travel down the inclined Way of the opposite Wing of the'same escapemeut-lever, and thereby prevents all jar or click in themovement and provides an alternate continuous reciprocation of saidrods, which is further attained by having the contact-rollers disposed,so that when the piston-rod upon one side of the gear- Wheel is ateither end of its stroke the oppositel rod upon the opposite side ofsaid wheel is at the center point or midway of its full stroke.

At the end ofthel air-compressors adjacent to the large gear-wheel' F isthe spring powertwo large gear-wheels and'mechan ism just described.Upon al suitable base or frame K is centrally mounted thecentral shaftL, car'- rying a drum l, over which the springs Z', f1tti'ng one withinthe other, are Wound and the free end-s thereof are secured to asuitable adjacent rigid connection, which allowsthe springs to be Woundup and unwound readily.

shaftL is's'ecured the small gear-Wheel M, that same size and mountedupon the stationary shafts n, arranged in a series concentric with the'motion to the central gear-Wheel M, with which the same intermesh.Beyond theinner gear-Wheel M upon the central shaft is mountedthe largerspur Wheel O, which meshes with the pinion P adjacent thereto andrigidly mounted upon the shaft p, which also carries directly back ofthe pinion P the large beveled gear-wheel Q, which is engaged by thesmall beveled gear-wheel R, carried upon the innermost end of the shaftS, and Whichis provided upon its outer face with the clutchfr, securelyfastened thereto and designed to engage the notched hub of the spurgear-Wheel T, loosely mounted upon said shaft S, and when' rotated bythe mechanism described communicates motion to the large gear-Wheel F,With Which the same meshes at one end of the pairs of cylinders.

A collar U is adj ustably mounted upon the shaft S by means of theset-screw u and is designed to form a stop for the coiled spring V,interposed between the same and the outer hub of the gear-Wheel T, andthus normally holds the same into engagement with the clutch r. When itis desired to Wind the motor, the shaft S is rotated by means of acrankhandle applied to one end thereof, and thus through the beveledpinion R communicates motion from the large gear-Wheel O through thevarious smaller gear-Wheels carrying the actuating-springs referred to,during which Winding the said gear-Wheel T, by means of its ratchetconnection With the clutch r, is not revolved; but When it is desiredfor the motor to Work the tension of the various springs causes motionto be given to the large vcentral Wheel O, Which in turn, through thesmall pinion and bevel-gear, causes the Wheel vT to revolve and in turnoperates the gearj Wheel F, which causes the mechanical movement hereindescribed to op'erate'inl the manner as fully set forth.

Having thus described our iuventiomwhat We claim, and desire to secureby Letters Patent is motor: J, from which motion is impartedvto the l.In a machine of the class described,the
